Abstract (en)

An antenna including a magnetic core (10) made of a soft-magnetic non-electro conductive material, including four corner protuberances (11) defining two orthogonal winding channels (12) around the magnetic core (10); X-winding (DX), Y-winding (DY) and Z-winding (DZ) of conductive wire orthogonal to one another wound around said magnetic core (10), wherein the antenna further comprises a first soft-magnetic sheet (21) attached superimposed on said four corner protuberances (11) of the magnetic core (10) providing a limiting edge (20) for the Z-winding (DZ), so that an increase of the sensitivity of the Z-winding (DZ) and a reduced thickness of the antenna in the Z-axis (Z) direction are obtained.
